WELCOME TO THE REACTION CHAMBER

Every shape tells a story.

Study the enzyme. Find the substrate that fits. Keep reacting as inhibitors and shifting conditions raise the pressure.

HOW TO PLAY

Match the chemistry.

01

Read the active site

The pocket shape and glyph identify the target. Find its complementary substrate.

02

Choose before it passes

Click or tap a molecule, or press 1–4. Correct picks score; wrong picks break your streak.

03

Adapt to interference

Striped competitive inhibitors mimic substrates. If conditions drift, stabilize the enzyme before matching.

Controls: 1–4 select molecules · P pauses · M toggles sound · Escape closes a dialog. The timer pauses when the tab is hidden.

This game models enzyme specificity and inhibition conceptually. Molecular shapes are simplified for play.
